Summit has been tremendous fun car! Beyond my wildest expectations!


Here are some videos of it in action:








Wide block with B2600 tranny is so 2005 ;) Bill Hitcher has made an adaptor to attach narrow block 4G63 to just about EVERY popular RWD transmission! At 1/3 the price of other vendors!

The lesson here is that if anyone driving a minivan ever challenges you to a race, politely decline.

But what if you're in a minivan too? ;)

So long as it's this one:

Unrelated: these folks have welded the majority of two LS1 engines together to make a 9 liter V12:



No idea if they have one up and running yet.

You should see the little 4 banger they make from the scrap.

I'm pretty sure I've seen them both run, though it's been a few years. One was a black suburban.

Why didn't they make a V16?

Can you imagine the sound inside that F1 minivan?

This thread is winning!

OK guys, the E Manage is out. I can’t say that I was happy with the way it was installed (I saw all type of electrical connections: solder, crimp and vampire clips...) but that is all undone now. Prior to removing it, I would get a quick spark whenever I put key in the “ON” position, but there would be no spark while I am cranking. Now that E Manage is out, I get no such initial spark and it is still not sparking when cranking.


This leads me to a two questions:

Is that initial spark an E manage thing or all Miata’s do this?
I suspect that ECU must get a signal from CAS in order to fire coils and fuel injectors, while cranking. How can I test if ECU is getting that signal?


Thanks

It is not normal for the ECU to generate an initial spark at power-on. I can't speak to whether E-Manage ECUs cause this.




Do you have spark and / or fuel while cranking? If so, the ECU is getting the CAS signal. If not, the ECU is probably* not getting it.

Does the fuel pump at least prime when you turn the key on? (You should be able to hear fuel flowing through the pressure regulator at the back of the fuel rail.)

No, there is no priming of fuel pump or any fuel in the return house hose. I suspect that ECU might be fried. I might take it apart and look for some obvious damage.

Where is MPI relay on a Miata?

Voltage was most certainly was interrupted to the coils. It was going through the Emanage first, so that could account for the initial spark. But if ECU was dead, there would be no further sparking. Injector triggers were tapped in parallel, so they never completely interrupted the wire.


Edit: Now that I think about it, there is no CE light, which I assume, must appear when you first turn on the key. So yet another indication that ECU is not righit.
